Answer:
By looking at the table we can determine that each element of the domain is paired with exactly one element of the range. Hence, it is a function.
<h3>D:</h3>
The domain of a function is the complete set of possible values of the independent variable in this case
<h3> -2 ≤ x ≤ 2</h3><h3 /><h3>R:</h3>
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain in this case it will be
<h3>5 ≤ y ≤ 9</h3>
10 feet is 120 inches. So your answer is 10 feet. Hope this helps:)

Answer: 30 degrees</h3>
========================================================
Step 1) Find angle EDC. This is the missing acute angle of the right triangle. Let's call this angle x for now. This angle x adds to the other acute angle (31) to get 90, so 31+x = 90 which solves to x = 59 when you subtract 31 from both sides.
Step 2) Add angles EDC and ADE to get 59+60 = 119. So angle ADC is 119 degrees.
Step 3) Using the idea that adjacent angles of a parallelogram are supplementary, we add adjacent angles ADC and BCD to get 180. Let y be the measure of angle BCD. So we have 119+y = 180 which solves to y = 61
Step 4) Let z be the measure of angle ECB. This adds to angle ECD = 31 to get the measure of angle BCD. So, z+31 = 61 solves to z = 30
